Abstract

Experimental tests for determining the mechanism of catalytic reactions were suggested. Quantitative relations were obtained that allowed the mechanism of formation of product molecules in an arbitrary catalytic reaction to be determined by isothermic relaxation methods. The relations found were compared with the literature data on the 2CO + O2 → 2CO2 reaction on the (111) surface of Pd. The experimental data were shown to be insufficient for the unambiguous determination of the mechanism of this reaction. The results available corresponded to the participation of physically adsorbed CO molecules in the formation of CO2. The temperature dependence of the reaction rate was determined by the transition of strongly adsorbed oxygen atoms into the mobile reactive state.
